    14.08.· The water level in the dissolved gas tank is an important factor affecting the air flotation effect. If the water level is too low, the necessary buffer depth will be lacking, and the gas will pass through the water layer to enter the air flotation device to form large bubbles, and the air flotation effect is not good. It is recommended that the water level be controlled within 1/31/4 of the

    18.06.· Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface, rather than allowing them to sink as in gravity thickening. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling.

    Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter
